The Support Vector Machine (SVM) solution corresponds to the centre of the largest sphere inscribed in version space. Alternative approaches like Bayesian Point Machines (BPM) and Analytic Centre Machines have suggested that the generalization performance can be further enhanced by considering other possible centres of version space like the centroid (centre of mass) or the analytic centre. We ...

Gravitational microlensing of quasars by stars in external galaxies can introduce fluctuations in the centroid of the “point-like” macro–images. The induced shifts are extremely small, on micro–arcsecond scales, below the limits of current optical observations. However, such shifts will become measurable with the proposed “Space Interferometry” mission, due to fly in 2005. The degree of the cen...

The asymmetric unit of the title compound, [PtCl(4)(C(12)H(12)N(2))], contains one half-mol-ecule; a twofold rotation axis passes through the Pt atom and the mid-point of the C-C bond linking the two rings. The Pt(IV) atom is six-coordinated in an octa-hedral configuration by two N atoms of the 4,4'-dimethyl-2,2'-bipyridine ligand and four terminal Cl atoms. In the crystal structure, there are ...

In the crystal structure of the title compound, C(12)H(14)N(2) (2+)·2C(7)H(5)O(3) (-), the cations and anions are linked via N-H⋯O hydrogen bonds and weak inter-molecular C-H⋯O inter-actions also occur. π-π stacking is observed between the nearly parallel benzene and pyridine rings [dihedral angle = 6.03 (8)°], the centroid-centroid separation being 3.7546 (16) Å. The 4,4'-(ethane-1,2-diyl)dipy...

Due to the non-line-of-sight (NLOS) and multipath fading channel (MPF) of the wireless networks, the non-existence of the intersection point often occurs in the range-based localization methods, e.g., the centroid-based trilateration method. To alleviate the problem, a confidence-based intersection method which expands the range of the circle within a certain confidence interval is proposed. In...
